I think that there are other problems here though; if you are going to be a part of an environment where you may experience adrenaline surges, you need to work through them. Skipping that part of an interview means that you won't be able to evaluate that response. One solution may be to include a high-stress part of the interview, but to weight it in the overall evaluation appropriately.

Climbing a tree won't get you away from a tiger; it's a cat.]
